What could it be cam sensor or crank sensor because it starts and then quits after 5 minutes what could it be ???

My car has 264000 miles.
My car has an automatic transmission.

You may have a cam or crank sensor problem or an electrical issue. You will need to see if the engine has no fuel pressure or spark and test computer to see if there is codes stored to diagnose the no start. Have a mechanic like one from YourMechanic come and check the no start for you.
